摘要：

We consider dynamics of entangled telechelic ionomers in the limit of strong association, where there are no free chain ends. Stress relaxation occurs in such a system by an exchange between pairs of chain ends in the associated state. For complete relaxation of stress, an exchange event must take place on every entanglement strand. However, diffusion can occur on an arbitrarily shorter time scale, leading to the interesting result that chains can diffuse distances many times their coil size without relaxing stress.
